Policy-based admission control in GMPLS optical networks

In this paper we present a policy-based admission control architecture responsible for managing the installation and aggregation of packet-based LSPs within lightpaths (optical LSPs). We have defined some policies in order to reduce the optical network overhead to remove and reroute lower priority LSPs. The architecture is composed of an admission control and a policy manager and the performed simulations indicated that the number of LSP removals is smaller when policies are applied.
